DETACHABLE METALLIC HEEL.

Application led December 26, 1919.

To all whom it 'may concern:

Be it known that I, RUDOLPH C. Rufrznn, a citizen of the United States, and a resident of lVellston, St. Louis county, Missouri, have invented a new and useful Improvement in Detachable Metallic I-Ieels, of which the iollowing is a specification.

This invention relates to metallic heels for shoes and has for its principal object to provide for the attachment of a leather or rubber tread-lift to the metallic shoe heel and for the removal of the lift, when the same becomes worn, without disturbing the heel itself.

The invention consists principally in the manner of securing the tread-lift to the base of the metallic heel. The invention further consists in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing which forms part of the specification and wherein like symbols refer to like -parts wherever theIy occur,

igure 1 is a perspective view of a shoe showing a heel embodying my invention secured thereto;

Fig. 2 is a central longitudinal section taken through the heel and shoe;

Fig. 3 is an elevation of the lower portion of the front face or breast of the heel, the lower corner of the heel being shown in section; and

Fig. L1 is a bottom plan view of the heel, the tread-lift being shown broken away to disclose the insert block located beneath.

In the drawing, 8 indicates a shoe, which may be of any desired type; 9 indicates the sole of the shoe and 10 indicates the body portion of a metallic heel shell.

The tread or base portion of the metallic heel shell 10 is provided with a pocket or recess 11 which is widened out above the base of the heel forming flanges 12 which extend continuously around the rear and side portions of the base of the heel. The pocket 11 is extended through the front face or breast of the shell forming an opening 13 therein, and the remaining metal forms. a bridge piece 14 which connects the opposite ends of the flanges 12. A leather or wooden block or insert 15 is inserted through the opening 13 into the pocket 11 and is preferably held therein by means of a nail or pin 16, which extends through a hole in the flan e Said pin is clenched on the upper sic e Specification of Letters Patent.

of the insert 15 by the striking thereof against the top of the pocket which thus acts as an anvil to turn the same. A tread-lift 17 of leather or other suitable material is secured to said insert 15 by means of nails, which are driven through the lift into the insert adjacent to the flange 12 and are clenched on the upper side of the insert by striking the top ot' the recess.

An anchor member, which forms means for attaching the metallic heel 10 to the shoe, is secured to the sole of the shoe and comprlsesa hub portion 18 having an inclined rim portion 19 located above the hub portion and is securely fastened to the heel portion of the shoe sole by means of nails 21 which are driven through a series of holes formed in the rim portion 19 of the anchor member.

The heel shell 10 covers the anchor member and is secured thereto by means of a screw 23 4which has its head portion located in a counter-sunk hole in the top of the pocket 11 in the base of the heel shell. This screw extends upwardly into the interior of the heel shell and its upper end is threaded into a threaded bore formed in the hub portion 18 of the anchor member.

With the above described arrangement, it is evident that the heel shell can easily be attached and detached. The heel shell and anchor member can be transferred to another pair of shoes when the shoes become Worn out and the tread-lift can be removed from time to time and a new one substituted with little effort.

The above described arrangement is considered only as an example and as the one best adapted to the design and shape oi shoe and heel shown but I do not wish to be limited thereto as the invention is applicable to other styles of shoes and heels.

What I claim is:

1. A shoe heel comprising a metallic shell having a recess formed in its base and an inclosed opening extending through one of the walls of said shell and communicating with said recess, a block of penetrable material adapted to be inserted into said recess through the opening in the wall of the shell and a tread-lift secured to said block.

2. A shoe heel comprising a metallic shell having a recess formed in its base and an inclosed opening extending through the breast of said heel and communicating with said recess, a block of penetrable material adapted to be inserted into said recess through vthe opening in the breast of the heel, and a tread-lift secured to said block.

3. A shoe heel comprising a metallic shell the flanges surrounding the same, said block being adapted to be inserted into said recess through the opening in the breast o the heel, means for securing said block in said having a recess formed in its base and an-i-nrecesa and a tread-lift secured to said block.

closed opening extending through the breast of the heel and communicating with said recess, said recess being widened out above the base of the heel, a securing block of penetrable material located in said recess, said block being adapted to be inserted therein through the opening in the breast of the heel, means for securing said blockin said recess, and a tread-lift secured to said block.

4. A detachable shoe heel comprising a metallic shell having a recess formed in its base, said recess being widened out above the base of the heel to form flanges which surround said recess, and extending through the breast of the heel in the form of an inclosed opening, a'block of penetrable material located in said recess and supported on 5. A detachable shoe heel comprising a metallic shell having a recess formed in its base, said recess being widened out above the base of the heel to form flanges which surround said'recess, said recess extending through the breast of the heel in the form of an inclosed opening, a block of penetrable material located in said recess and supported on the anges surrounding the same, said block being adapted to be inserted into said Y recess through the opening in the breast of the heel, a pin extending through said flange and said block for securing the same in said 40 recess, and a tread-lift secured to said block.
